IMPROVEMENT lN GUN-SWABS.

Specification forming part of Letters Patent No. 211,555, dated January2l, 1879 application filed June 8, 1878.

To all whom it may concern:

Beit known that I, HARRY OoMsTocK, of New York, in the county of NewYork and State of New York, have invented certain new and usefulImprovements in Gun Cleaners or Swabs, of which the following; is aspecifica tion:

' This invention relates to an improved swab or cleaner for nre-arms,and is designed especially for that class known as choke-bore guns, inwhich the bore is made to vary in caliber at different points throughoutits length.

My invention consists in the combination of a head, spring-arms providedwith shoulders, and pads arranged between said shoulders, as will morefully hereinafter appear.

In the drawings, Figure l represents a side elevation of my improvedswab or cleaner. Fig. 2 represents a sectional view ofthe same. Fig. 3is a side elevation, showing the springs compressed. Fig. 4 representsan end view. Fig. 5 is a detached view of one of the pads.

The letter A represents a metallic head provided with a screw-threadedshank, by means of which it may be attached to the end of a ramrod of agun, and B C represent two spring-arms, secured to said head, andexpanding toward their lower or free ends when in their normal position.These spring-arms are removably attached to the head A by having theirinner ends placed iiatwise together, and inserted in a socket cuttransversely through or across the end of said head, and thus secured bya rivet, a, the hole for which is at right angles to the socket. By thisconstruction, it will be seen, I am enabled to form the spring-arms andtemper them separately from the head, which may be of cast metal, andshouldone of the arms become broken, it can be easily removed andreplaced by another without necessitating the loss of the wholeinstrument. To the ends of said springs, on their outer sides, aresecured elastic or yielding pads D, which may be constructed of anysuitable material-such as felt, leather, cork, hair, bristles, wire, orthe like.

In the present instance the pads are represented as constructed of felt,and the arms are constructed with shoulders d d, between which said padsare held. being secured by means of pins e e, passing through theshoulders and longitudinally through the pads.

I have above described one form of my improved invention but it isobvious that it can be variously modified without departing from itsnature and spirit. For instance, the head to which the springs areattached may be formed directly upon the end of a ramrod, or said headmay be entirely omitted and the springs formed with a shank to beattached to the end of the ramrod, or the springs may be attacheddirectly to said ramrod.

Again, instead of forming the springs with shoulders, and securing thepads thereto by means of pins, other methods of fastening th-e same maybe employed if found desirable.

The operation of my improved swab or cleaner will be readily understoodin connection with the above description. In inserting it in the gun thespring-arms are pressed together by hand until the swab will readilyAfter its insertion the pressure is reenter. moved, allowing the'springs to expand and press against the sides of the bore; and as theswab is passed through the barrel the springs will be automaticallypressed together or exy panded, according to the varying caliber ofthebarrel, thus insuring the removal of dirt or deposits from all parts ofthe bore alike.

l. The combination of the head A, springarms B O, provided withshoulders d d, and the pads D D, arranged between said shoulders,substantially as described.

2. The combination of the head A, springarms B C, provided wit-l1 theperforated shoulders d', the segmental pads D D, and pins c,substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand inthe presence of the subscribing witnesses.

HARRY OOMSTOGK.
